Endurance training induces several significant physiological changes within the body. Primarily, it enhances cardiovascular fitness, increasing the heart's ability to pump blood more efficiently and improving oxygen transport. Muscle adaptations include an increase in mitochondria, which boosts energy production. Additionally, endurance training improves the body's ability to utilize fat as fuel, sparing glycogen stores for longer activity periods. Furthermore, regular endurance training strengthens ligaments and tendons, enhancing overall musculoskeletal health. These adaptations collectively contribute to improved performance and stamina.
